In build 33, there is a new update that we can play lessons in audio-only aside from video. And it's working pretty well. 

Welcome, I am also new here.

Your welcome!

I noticed this version allows you to do it now. Thank you! It is much more convenient!

The function is not working at all for me. What should I do?
Has anyone been able to find a solution? I updated to version 28 and no character is loading from the writing section.

For this lesson, I tested every character and this is what I got:
Working Characters: 你, 做, 不, 那, 是, Not working characters: 甚麼, 工作, 大學生 Maybe it can help you to detect what is going on.

I have been testing this more. It does not matter whether I use traditional or simplified characters. It seems that there is a specific list of characters available.
I attached pictures of the same lesson using both styles. However, only two characters are available. The other four get stuck loading forever. It does not matter if I use simplified or traditional characters anyway.

The new version now allows you to use your google account! I have not tried using Facebook, but my google credentials worked great!

Even those from the most basic lessons are having the same issue. This screenshot is from the hello and goodbye lesson.

I am also facing the same issue as you. I took the liberty of taking some screenshots from the first sentence in lesson two. Only 1 of the three characters appears.
I hope you can solve this issue. It is a very good function!

I kept testing the function, directly from the lesson screen.
In the picture, you can see that the new function works. However, not every character is loading. It seems to be a common problem across different lessons. I attach screenshots from lesson one. only Hen and Ni load, while other characters get stuck loading forever.

I kept testing and realized that Pinyin Programs #6, #7, and #8 also have the same issue.
It seems that also the website version is missing the text. It would be great for learners to be able to see the combinations of pinyin that make the sound (For example, Da, Ta, Na, La, etc.).

I found the same problem as you did with Pinyin Programs #3, #4, and #5. I will keep testing the following lessons to report back other issues.

Small visual suggestions:
1. You should add a visual aid that lets you know when you have already passed a lesson. I know there is a complete lesson inside each lesson. However, I feel it would be better if users did not have to load every lesson over and over to check whether they already passed it or not. For example, you could change the color of the lesson's banner or darken it once it has been completed. That way, users would save time. 2. When the introduction text fits the limit of the app, it should not show the collapse/expand arrow. For example, in the lesson saying goodbye, from the newbie's area, the text is not long. However, it still shows an interactive button that makes me think perhaps there is some text missing. It gives the users the idea that the text files are either missing or not loading. When in fact they are complete.

Yes! That would be a great way to easily show the errors.
Additionally, I would love to be able to add multiple pictures when adding a new topic. As of right now, I can only do that when I reply to a comment. It is strange that I cannot do it on the actual topic creation page. Sometimes I need to upload more than one to show a point. Being able to upload a video would be even better. Great Idea!

CPod Writing UI suggestion.
It would be great if you could add any visual aid to characters one has already mastered (Getting all the strokes right at least a couple of times). As of right now, all of them look the same. No matter If I already did them 100 times or 0 times. Maybe you could put a start or a check next to the character, or change its color so the user can focus on the ones he or she has not mastered yet.
